The sum of all exterior angles of a triangle is
(a) 180°
(b) 360°
(c) 540°
(d) 720°

Solution:

We have to find the sum of all exterior angles of a triangle.

A triangle is a simple polygon with 3 sides and 3 interior angles.

A triangle is a closed shape with 3 angles, 3 sides, and 3 vertices.

We know that the sum of all exterior angles of any polygon is equal to 360 degrees.

Triangle is a 3 sided polygon.

Therefore, the sum of exterior angles of a triangle is 360 degrees.
